Abstract: Disclosed is a thin wire gridiron comprising a gridiron frame formed in a circular or polygonal shape and a plurality of gridiron wire made of a metal material and arranged and coupled to the gridiron frame. According to the present invention, a first end part of the gridiron wire is fitted into an elastic body having a through-hole formed in the center in a first inner space of a gridiron frame, a ring is formed on the first end part of the gridiron wire by the gridiron wire and is fitted in a locking ring, and the locking ring has a size that does not pass through the central hole of the elastic body and is locked on the elastic body. Accordingly, both ends of the elastic body are locked and contracted by the inner surface of the gridiron frame and the locking ring in the first internal space to provide elasticity, so that the gridiron wire is pulled toward a first distal end by the elasticity of the elastic body disposed in the first inner space, thereby being elastically fixed to the gridiron frame. Since the thin wire gridiron can use a gridiron wire of a fine thickness, a phenomenon of food sticking to the gridiron wire and burning when grilling ingredients is removed, it is not required to replace the gridiron and cleaning is facilitated. In addition, the gridiron wire is prevented from sagging even if the gridiron wire is stretched by heat applied to the gridiron and manufacture is facilitated due to a simple structure.
